I was thrashing about in the Leaf's menu system and found lots of interesting pages.
This one was the most interesting...
Right now, the charge point I am using, that is one block away, is free, so that's very good economy.
If I am using house power, that is currently running $0.11/kW-hr.
So that would work out to...
$/mile = 4.1 miles /kW-hr = .11 /4.1 =
$0.027 / mile
GeoNRGee said that the price of electricity from the EV stations in Seattle was $0.44/kW-hr, or 4X home charging. It's more expensive, but they do have the expense of constructing the infrastructure to recuperate.
So that works out to .44/4.1 =
$0.11 / mile
My daughter just bought a New Honda Odyssey Van that gets about 19 miles to the gallon...
With gas currently at $3.14/gallon, that works out to 3.14/19 =
$0.17 / mile
National average miles per gallon is currently 23.6 mpg
That's 3.14/23.6 =
$0.13 / mile
My 2000 Honda Insight gets around 55 mpg (avg summer & winter) around town.
That works out to 3.14/55 =
$0.06 / mile
If I am out on the highway, and keep my Insight at 55 mph, it can get around 73 mpg.
That works out to... 3.14/73 =
$0.043 / mile
All of which makes an electric car a very economical alternative to just about everything except bicycling.
Best,
